Field Setting Parameters For Smart Plumb Cylinder Units - 3 Zone
If you set a field setting and go back to check it, it will not have changed. The field
setting does not get written to th PCB unless you push SET after changing it.
Field Setting Set To
Description
20-11
-2
Low ambient temp setting for optimisation.
20-12
+15
High ambient temp setting for optimisation.
20-21
40°C
Maximum flow temperature for heating circuit 1 at set value of 20-11.
This should be set to the designed flow temperature used to calculate
the size of the underfloor heating system. If the underfloor has been
designed and supplied by Joule set the temperature to 40°C.
20-22
35°C
Minimum flow temperature for heating circuit 1 at set value of 20-12.
This should be set to 35°C.
20-31
48°C
Maximum flow temperature for heating circuit 2 at set value of 20-11.
This should be set to the designed flow temperature used to calculate
the size of the radiators. If the radiators have been sized by Joule set
the temperature to 48°C.
20-32
35°C
Minimum flow temperature for heating circuit 2 at set value of 20-12.
This should be set to 35°C.
20-91
1
This tells the system to use the run signal from Zone 1.
20-92
1
This tells the system to use the run signal from Zone 2.
30-11
1
Tells the unit it has a cylinder connected.
30-25
200L cyl.=50min
300L cyl.=90min
Maximum cylinder heating time from heat pump before turning back to
heating zones.
30-32
200L cyl.=50min
300L cyl.=90min
Maximum cylinder heating time from heat pump before turning on im-
mersion to support it.
30-42
T (Tuesday)
Legionella function activates on this day.
30-43
3am
Legionella function activates on this hour.
30-44
60°C
Legionella function raises water temp to this.
30-51
-
Enables the timer for DHW Boost mode.
30-52
60
Should automatically be set to 60 minutes, this is the max time in boost
mode before the unit reverts back to normal operation.
Once the parameters have been set, push the Escape key once and the controller should revert
back to just showing the time.
